Lets set up our values first:

She starts out with -50 because of the table charge.

Then she earns $2 per print written as 2x

Her net profit will be y and the equation is as follows:

2x - 50 = y

------------------------

Now she wants a profit of $130 so we set y = 130

2x - 50 = 130

Solve:

2x = 180

x = 90

-------------------------

She is there for a course of 3 days so we jist divide the amount by 3:

90 / 3 = 30 prints a day
